The 4ES electric submersible pumps are suitable to delver a wide range of liquids including chemically aggressive water, with maximum 40g/m suspended solids. Maximum running time at zero delivery (closed gate valve): 2 minutes.
Maximum pumping water temperature, minimum motor cooling water capacity, operating position, supply voltage, pump rating and other technical data can be found in the relevant tables.


Hydraulic pump performance refer to cold water (20) at atmospheric pressure (1 bar) according to ISO 9906 - Annex A norms.
Performances indicated in the catalogue refer to liquids with volumic mass of 1kg/dm and with kinematic viscosity not higher that 1mm/s, not including losses in the non - return valve
